SPECIFICATION forming arser Letters Patent No. 363,190, dated May l7,1887.-

A nplication filed Septrmber 9, 1886. Serial No. 2l3,103. (No model.)

is termed in the art as crackling the surface of the opaque glass. Inthe drawings To all whom/it may concern.-

Befit known that I, J OSEPH WEBB, asubj ect of the Queen of GreatBritain, residing at Ben.- ver, in the county of Beaverand State ofPenn- 5 sylvania,have invented certain new and use- I accompanyingdrawings, which fd'rm part of this specification.

This invention has relation to a method of manufacturing fancy glass,and has for its ob ject the provision of a. method of manufacturingfancy glassware or articles or pieces of glass heretofore unknown.

. This invention consists in the production ofglass articles by firstforming a body-section cylinder, or other form of opaque glass,with

goilldfllltfit-lOllS, cavities, or depressions in its surface, and whilethe indented opaque glass is still warm placing upon its indentedsurface a film,sheet,or coating of transparent glass the opaque body orsection A is shown as being of the ordinary pearshaped form which a 5mass of blown glass first assumes.

B designates a transparent film orsurface which is to be applied to theopaque section A. Said film is of a cup shape, and I also pre fer toform it by the ordinary and well-known 6o process of blowing. After the'opaque section A and the transparent section'B have been formed, asshown, and. when the opaque section has been allowed towel to such adegree that it will retain its shape, and while the transparent cup Bisstill hot enough'to adhere thereto, the opaque section is inserted intothe transparent cup, and the mass is then rolleduponamarverorotherfiatsnrface. Thetra'nsparent film now adheres firmlyto the raised portions of the opaque section, thereby confining the airin the recesses or indentations a a a. The article so formed'is nowoneintegral mass of. glass, having bubbles'of air between its 5processes of i'nanufacturing glass; but the preferable formjor manner ofmaking it is to blow F-' recesses, or cavities on the surface of the 5oopaque section;

in a heated condition, and then pressing the 2 5 transparent film intocontact with the opaque. glass, so as to incorporate it therewith,thereby confining the air within the indentations or cavities in theopaque glass, and, finally, in roughening the transparent film by theuse of 0 acid or otherwise, in order to produce the desired effect.

In the accompanying drawings, in 'Figure l is shown the section, body,or piece of opaque. glass in the condition in. which it appears 5 forethe attachment of the transparent coating or film. In Fig. 2 is shownthe transparent film ready for applieatiou'tdtlie opaque sec-' tion, andin Fig. 3a sectiohial view of theopaque section and the transparent filmto- 40 get-her. I ,A designates the opaque vbody or section, havinguponits surface indentations, cavities, or recesses a aa. The opaquesection or body A may be produced by any of the well-known opaque andits transparent walls, and may now 7 5 be reheated and fashioned intoany desirable arlicle-such as a tumbler, pitcher, globe, shade, &c. e

\Vhen the article is formed. as described, the surface of thetransparent film is roughened Sc by means of acid, or by any suitablechemical or some chemical process, and this rougheping will verymaterially add to the effect-produced by the refraction of light in andbythe cavitics or indentations between the two filn' s,'the pencils orrays of light bcingbroken lipordecomposed by the roughened film andcaused to impart to the surface a beautiful effect of delicate prismaticcoloring or iridesccnce.

It is obvious that the method above de- 9( scribed may be variedinqniany particulars without departing from the" spirit of my-invcntion;For instance, the transparent film may he placed on the interior of theopaque body, instead of upon the outside of the same, in 93 which case,of course, theindentations orcavities will be formed upon the interiorsurface of the opaque section. Again, the indentations or cavities maybe formed upon the transparent film, while the opaque section is made nperfectly plain.

I am aware that it is not new to produce ar-' it in a suitable moldhaving elevations upon its surface adapted to form-the indentations,

butxthcsc indentations, recesses, or cavities may be produced by'what i5 the glasswa' aware eemposed oi' two films of ervening air-spaces byplacing eams or strips f glass and weiiithe inner and enter cups; hemebroadly, my invention the iii glassware (if this iieseription l Wiiiiieeluiiesi air-bubbles, the .e eeing eeseriiieii in'Englisii' Patent-No. 2 i5 05 I wish ii; t0 be enderstoed that '1 do not 'iieicein claimas a. new article of manufae'eu're a hereinieseriimd when the same lpenmnee--timb ism'hei'e ad from ene c0102? inte ani Qiigi i'fl presentsthe tie? 03 her, e
